Free will defense

The Free will defense is a apologetical argument posited by Alvin Plantinga as a defense for the Problem of evil, and is widely regarded as valid and a sufficient defense by many Contemporary Philosophers. The argument holds that; "It is possible that God, even being omnipotent, could not create a world with free creatures who never choose evil. Furthermore, it is possible that God, even being omnibenevolent, would desire to create a world which contains evil if moral goodness requires free moral creatures."
